> It's not only a crime, it's an extremely serious crime. What on Earth are you talking about?
Today it is. Back then it wasn't. (Or rather, it wasn't seen as such.) It was, by definition, a number that people made up based on their gut feeling (NOT hard data), and there was no regulation or precedent for what sort of number you could make up.
Notice that in the linked article, the Bank of England carefully doesn't deny putting pressure on banks to keep Libor low, and just says that: ""
Or see the article I linked elsewhere in the thread about Barclay's who was perfectly open with analysts and regulators that they were lying about Libor to improve their share price: http://dealbreaker.com/2012/07/same-old-boring-story/
Yes, we see it as a serious crime now, but it's pretty clear that circa 2007-2008, that was not a common view.
> LIBOR is a derivative of daily rate data which is shared between banks [...] You can't tell investors that the rate is based on a daily measurement of interbank risk
It's neither of those things, and I certainly hope investors weren't being told that, because that would be a lie. It's literally the result of asking some banks, "hey, if you went and borrowed some money...how much do you reckon you'd get charged?". And it turns out that's horribly subjective, not very useful, and prone to manipulation!
